We are updating so we can shuffle down phones to the wife and son. I plan on upgrading every 2 years once my contract ends, so in 2 years I'll upgrade again. It used to be every year back when they added decent things to each phone, but alas now that's not quite as common.Well its the , almost, same for factor and the 6s or 6 are still fantastic phones, I am upgrading from an iPhone 5 and It will be a major upgrade and I don't intend to upgrade again until either a new design , stunning , or my phone gets slow or breaks.
